Which is better? 4 bolt main or 2 bolt main?

I'm buying a 1993 z28 camaro this weekend. It has no engine and no transmission so I plan on putting all of this in it. I'm putting a 350 V8 in it. This car is going to be my daily driver when I'm done. My question is which should I use? I know the 4 bolts are stronger and 2 bolts can withstand up to 6000RPMs and up to 500HP. I plan on putting a turbo (possibly twin) at some point. Will I need a 4 bolt undoubtedly or am I good to use a 2 bolt main? How much HP would I be putting out?

4-bolt main bearings, are better. It's solid. You can squeeze out over 600hp, through camshaft and head tuning. The 4-bolt is the way to go- if you plan on turbo-ing the motor.
